POWER HAT-PRESS.

To all who/mit 'may concern:

Be it known that I, CHARLES A. BINGA- LMAN, citizen of the United States, residing at- Readinof, in the county of Berks and State of Igennsylvania, have invented certain new and useful Improvements in Power I-Iat-Presses, of which the following is a specification.

This invention relates to improvements in hat presses and my object is to provide a machine in which the finishing pressure or gloss is applied to a hat.

The device is construct-ed to operate .with compressed air as the pressure medium though it is evident that water may be used with equal facility.

The machine includes means for raising the pressure chamber from the die which consists of an automatically operated weighted lever and its connections; a foot lever for closing these parts, means for automatically locking the parts in closed position and, a vhand lever for opening said locking means thus permitting said weighted lever to again operate to open the parts for the next operation.

The invention is more fully described in the following specification and clearlyillus trated in the .accompanying drawing7 in which Figure 1 is a front. elevation, partly in section, showing the machine just ready to press a hat. Fig. 2 is a side elevation of the machinein Ithe same closed position shown in Fig. 1. .Figz 3 isa sectional view taken 011 lines indicated in Fig. et showing a portion of the upper surface of the die and also a section through the burner cham ber. Fig. l is a central vertical section on lines indicated in Fig. 2 showing the pressure chamber raised and a pressed hat in position in the die. ready to be removed. Fig. 5 is a frontelevation of the upper portion of the machine, open. 4Andl Fig. 6 is aj detail ofthe spider.

The numeral 1 designates the machine frame which comprises two like uprights provided with a connecting table 52 on which rests the bed plate 3. On the top of this plate I locate a latching cam 35 adapted to Speccation of Letters Patent.

l move thereon in a horizontal plane.

bed plate 3 is formed with a central hub or tubular portion 5, screw-threaded internally and around which the latching cam turns. A screw-threaded disk 6 is located in this hub and is moved np and down therein by means of a bevel gear 7 attached to the shaft S on., which the-disk is mounted and which is operated from the outside of the machine by a hand crank engaging the end of the shaft 9. This disk forms a support for the removable die 10 and is vertically adjustable so that it may accommodate itself to difterent sizes of dies. This support is necessary for the reason that the dies are ordinarily made of soft metal and the pressure applied to the inside thereof has a tendency to change its shape if not properly supported.

Immediately above the bed plate 3 I form a combined die support and burner chamber 11 in which I locate an annular gas burner 12 (shown in Fig. et) and this chamber is formed with suitable vent ,openings 13.

The iang'e of the removable die 10 rests the body or crown portion depends into the tubular portion or hub 5 of the bed plate, so that it is evident that the heat will-be uniformly presented to the die while a hat is being pressed.

In the frame uprights 1, are formed `guide ways 1l and in these I place vertical rods 15 and to the top. of these rods I securea cross-head or spider 1G and to this spider I secure the pressure chamber 17, ot' dome shape, provided with a flange 18 and between this iange and an annular ring 19, of the same diameter, I place a rubber diaphragm Q0. Through the center of the spider I adniit air under pressnre, to the dome like pressure chamber. The air is admitted vatthe top of the dome, in the center, through a distributer 21 which is provided with outlets 22 arranged at right angles to its axis. This is to prevent a direct jet of air against thediaphragm. `With this construction, the air strikes the top of the chamber and is so deflected that the pressure is uniform over the entire surface of the diaphragm. The

The

on the top of this burner chamber while` lower ends of the bars 15 are secured to a cross-head 23 adapted to travel in guide ways in the frame 1, and this cross-head is connected by links 24 to a foot lever 25, by means of which the pressure chamber is lowered. The cross-head is also connected by links 2G to levers 27 which carry a weight 23 and by means of which the pressure chamber is raised. To the spider 16 I also lsecure three rods 15a which pass through guides 32.a formed on the bed plate 3. These rods 15 are flattened at a point 30 about midway of their length in which portions I form an opening 31. The latching device, located on the bed plate 3, comprises a movable cam member and in the bed plate I form three approximately equi-distant pockets, 32 and in each is located a ra.

dially movable latch 33, each of which carries an upwardly extending pin 34 which ex- .tends through a registering slot 3a in t-li'e bed plate 3 and is adapted to engage and ride inone of the slots in the cam 35. This cam is formed 'with an operating handle 3G and is adapted to engage, when moved to the position shown in dotted lines in Fig. 3, a latch 3,7 is secured to the front of the machine. This latch -is connected by :l crank arm 3S to a. depending rod 31) which carries an adjustable nut 40.

011e of the vertical bars 152l is provided with a horizontal arm 41, so that when the pressure chamber and arms 15a are lowered. contact of the arm 41 with the nut 40 will open the latch 37 and release the handle 36 of the cam. The cam is provided with :1 spring 42 which is in tension when the cam is engaged in the latch 37 and when released as just described, the spring will return it to the position shown in full lines in Fig. 3 when the latches 33 enter into engagement wit-h t-he vertical bars 15a.

The operation of the machine is as follows z-Assuming that a hat is in the position shown in Fig. l, the machine is ready to press it. The air is admitted to the pressure chamber through the dist-ribut'er 2l, pressing the diaphragm 20 against the hat which is interposed between it and the die ,10 and when the pressure has been sufficiently applied, as indicated by any suitable instrument, 50, the air is released from the pressure chamber, by means of a suitable valve 5l; the hand lever 36 of the cam is thrown to the 'position' indicated in dotted lines in' Fi 3, When-it engages the latch 37, which hol s it until "released, 'as will be described later. This movement of the cam 35 will .Withdraw the latch members -33 from engagement with the vertical rods 15 and the weight2'8 on the lever 27, will raise the bars 15 and with them the spider 16 and the pressure chamber 17 to the position shown in Figs. 4: and 5; the hat is removed, another hat is placed in position in the die, the foot lever 25 is pressed down, drawing down the bars 15 and the pressure chamber and when the arm 41 on the end of one of Ithe bars 15 contacts with the nut 40 on the depending latch bar 39, thel latch 37 will be opened and the hand lever 36 of the cam willbe returned, through the tension of the spring 42, to the position shown in full lines in Fig. 3, when the latch members 33 will snap into engagement with the bars 15a, at their flattened perforated portions, and thus lock the parts in the position shown in Fig. 1, ready to again apply the air pressure.

Having thus fully described my invention, what 'I claim and desire to secure by Letters Patent is 1. 'In a hat press a frame, a pressure chamber, means for raising and lowering said chamber, a vertically adjustable die support, means for locking the chamber in closed position, said means comprising a cam and a series of radially movable latches, a latch for holding said cam in locked position, a trigger device for releasing said latch and means for autdmatically operating said trigger to lock the machine. I

In a hat press a. frame, a vertically movable pressure chamber, a spider to which the chamber is secured, upright bars carried by said spider, means for lowering said bars and chamber, a cam provided with a hand lever and radially operating latches adapted to engage and hold said bars in lowered position, a latch to hold the cam locked in open position, a trigger device adapted to release said latch by the downward movement of the bars, a spring for returning the cam to4 locked closed position when said latch is released, a cross-head connecting said bars at their lower ends, a weighted le-4 ver secured to said cross-head and adapted to raise said bars and pressure chamber when the radially operated latches are withdrawn, all substantially as and for the purpose set forth.
